With eight independent, full-featured compressor/limiters and gates, the ACP88 can solve a host of thorny studio and live-sound problems. A switchable power transformer enables international use.

Each channel provides a fully variable compressor with a sidechain send and return to enable spectral processing and ducking. In addition to the usual attack, release, ratio, threshold, and makeup gain controls, each compressor offers selectable soft- or hard-knee compression and an Auto Attack feature. A six-segment LED meter displays the amount of gain reduction, and pair of LEDs indicate gate position (open/closed) and compression threshold (above/below).
